Abstract: A novel apparatus and method for use in measuring surface slope is disclosed. In a preferred embodiment, the measurement apparatus includes a fluid case having an arch of flat segments forming a sloped ceiling. In another preferred embodiment, a smooth curve, instead of a series of flat segments, is formed by reducing the length, and increasing the number, of the constant slope flat segments. And in a preferred embodiment, the apparatus provides a mechanism for compensating for any expansion or contraction of the fluid in the fluid case. A method for measuring the slope of a surface includes providing a measurement apparatus, placing the measurement apparatus adjacent the surface and reading an indicator corresponding to the slope of the surface.

Abstract: An apparatus for conveying items to a selected receiving station comprises a round carousel rotatable about a center thereof to align a portion thereof with a selected azimuth, a platform disposed in the carousel, the platform being movable rotatably with the carousel and movable vertically in the carousel to a selected height, and a sled disposed on the platform and movable on the platform sidewise through a path concentric with the carousel to align the sled with a second selected azimuth, the sled being configured to receive thereon at least one of the items. The item is movable circularly by the carousel, vertically by the platform, and circularly by the sled, whereby to be conveyed to and from the receiving station disposed at the selected height and at the second azimuth.
